Had 2 Optima blue tops die on me in the last 2 months. One was just shy of 8 years old and the other not quite 6 years old. Both were heavily abused, the 2011 battery was in my car trailer powering the winch and the 2013 battery was the backup for the winch as well as used for jump starts, testing circuits and used powering sprayers. They often got run down to less than 3 volts and sat for long periods without being used or charged. Both were brought to the store for warranty replacement, I bought them for the core charge and charged them properly.
Replaced one today with a new yellow top that should give lots of years of service.
Have red tops in the Chevelle, Nova and my Silverado. Chevelle battery is new, the Nova battery is 4 years old and the Silverado battery is 5 years old. I seem to have good luck with these, I know some people do not. Bought my first red top in 1996 and have been using them ever since.
